Display Technology and Ambient Illumination Influences on Visual Fatigue at VDT Workstations
The concept of "visual fatigue" has been studied for 70 years or more. In that time, no single metric of measuring visual fatigue nor one agreed-upon set of tasks to induce visual fatigue has been settled upon. Not even a robust definition of visual fatigue has been established. This research …

Analysis of the Effects of Privacy Filter Use on Horizontal Deviations in Posture of VDT Operators
The visual display terminal (VDT) is an integral part of the modern office. An issue of concern associated with the use of the VDT is maintaining privacy of on-screen materials. Privacy filters are products designed to restrict the viewing angle to documents displayed on a VDT, so that the …

The functional characterisation of the XhABFA transcription factor from the resurrection plant Xerophyta humilis
Vegetative desiccation tolerance (VDT), the ability to survive loss of up to 95% of cellular water in leaves and roots, is rare amongst vascular plants. However, the trait has evolved multiple times in a small, diverse group of angiosperms collectively known as “resurrection plants”. The …

The Effects of Instigation, Experiential Avoidance, and Emotion Dysregulation on Dating Aggression
… test of aggression using the Voodoo Doll Task (VDT). College students (N = 269) listened to a neutral recording and then completed a behavioral measure of aggressive tendencies, the VDT. Participants then listened to a provocative jealousy induction scenario and again completed the VDT. Emotion …

Investigation of the effects of various types of realistic noise and music on a computer-generated graphics interpretation VDT task
Fifty-six subjects performed a decision and data-entry task (for 40 minutes) to determine the influence of realistic noises on task performance. Implementation of a mixed two-by-seven complete factorial design was used to investigate the influence of noise on a) objective performance measures …

Comparative analysis of desiccation responses in three Xerophyta species at two stages of seedling development
Vegetative desiccation tolerance (VDT) is a rare trait among flowering plants, enabling the adult tissues of certain species, known collectively as resurrection plants, to survive near-total water loss and revive upon rehydration. This study used a seedling model to investigate VDT at two …

Accomodation with displays having color contrast
… contributes to the visual fatigue experienced by VDT users. The increased use of multicolor CRTs in the workplace adds yet another factor, chromatic aberration, to affect the observers' accommodation to information presented on the CRT. Two experiments were run to determine the effect of viewing …

The impact of the introduction of visual display terminals on the job characteristics, job satisfaction and well-being of users in government offices
The proliferation of visual display terminals (VDTs) in offices is an international phenomenon. Numerous studies have investigated the health implications which can be categorised into visual problems, symptoms of musculo-skelctal discomfort, or psychosocial effects. The psychosocial effects are …
